My paternal ancestors are McLains and I have researched them back to Dublin city circa 1720 (the name then was mostly spelled Maclaine or Macklaine and they were Church of Ireland protestants). After submitting YDNA several years ago I got one 37-marker match which crossed my paternal line 9 generations ago which helped in my research. My other match was with someone named McLain but they only had 25 markers and the estimated match was about 20 generations but I believe it may be closer. Now onto what I need help understanding... In the 67-marker M222 worksheet done by Wilson and McLaughlin, I get that all the names are grouped in accordance with variation from the Modal Haplotype of M222. I am number 50 on the list (McLain) and I'm in a large group of Doherty-variant surnames. To be precise, numbers 41-58 are Doherty-variants except for me... But I have no Doherty 67-marker matches. Are these names so distant that I match them a thousand years ago? I have several 12/25 matches for Dohertys and the only other name thats come up more than once is Galyean/Gallion which is 3 or 4 individuals with variants of this name at 25 markers) In studying my own clan's genealogy, less than 10% of Maclean/Maclaine variants are M222 positive like I am and mostly are Celtic dna. I have taken this to mean that possibly some Dohertys crossed the Irish sea into Scotland between 1200-1500 and there was a non-paternal event of a Doherty child being accepted into the family. Would I be correct in this assumption? The other possiblity is that my ancestors were never in Scotland to begin with and a Doherty became a Maclaine much later between 1600 and 1700 a.d. just beyond my paper trail. Any help would be appreciated, Thank you very much! Chris (McLain) Beal
